ShadeMart 11ft x 13ft White Sun Shade Sail UPF50 Rectangle - Cool

Our review of the ShadeMart 11' x 13' white sun shade sail finds it best suited to homeowners and small businesses looking for breathable, UV-blocking coverage for patios, carports, and pool areas. The biggest reason to consider this shade sail is its fabric: woven HDPE with a UPF50 rating that blocks up to 95% of harmful UV rays while remaining water permeable, so it lowers temperature noticeably without trapping moisture. Installation is straightforward with the stainless steel D rings and heavy duty webbing, and the rectangle shape is a versatile, decorative solution for many outdoor spaces.

Key Features

• Woven HDPE fabric: Provides durable, fade-resistant shade and blocks up to 95% of UV rays for reliable sun protection.
• Stainless steel D rings: Each corner is reinforced with corrosion-resistant D rings attached to heavy duty white webbing for secure anchoring.
• Water permeable design: Breathable weave allows water and air to pass through, preventing pooling and reducing wind stress on the fabric.
• Temperature reduction: The fabric can lower ambient temperature by at least 10-15 degrees, making outdoor areas more comfortable in strong sun.
• Custom sizing available: Multiple sizes and custom options let you match the sail to patios, carports, pergolas, or poolside layouts.
• Rectangle styling: A simple shape that integrates with many outdoor designs and functions as both shade and decorative canopy.

Who It's For

The ShadeMart rectangle shade sail is ideal for homeowners who want a durable, breathable canopy to reduce heat and sun exposure on patios, decks, pools, and carports without creating a waterproof tent. It also suits DIY installers who can mount sails to poles, walls, trees, or existing structures using proper hardware kits.

Those who need full waterproof protection or expect heavy snow load should look elsewhere, and buyers who require an exact factory-cut rectangle should note that manual measurements can produce slight variations in shape even though the fabric area remains constant.

Pros & Cons

Pros

• High UPF50 fabric blocks most UV and reduces temperature effectively.
• Stainless steel corner D rings and heavy webbing make attachments secure and durable.

• Custom size options allow fitting to many outdoor layouts.

Cons

• Slight variations in rectangle shape can occur from manual measurement and cutting.
